Medicare's Hospital Insurance Trust Fund, which finances about half the health program for seniors and the disabled, won't run out of money until 2030, the program's trustees said Monday. That's four years later than projected last year and 13 years later than projected the year before the passage of the Affordable Care Act. Unlike Medicare, however, the part of Social Security that pays for people getting disability benefits is in far more immediate danger. The Disability Insurance Trust Fund is projected to run out of money in 2016, just two years from now, unless Congress intervenes, the trustees said.
